Leica Visoflex Lens Adapter $175 VEOS
Nikon F Lens Adapter (MF or AF) $175 NEOS

In my opinion, the CameraQuest NEOS and REOS adapters are BETTER their Novoflex counterparts, which often are a bit tight and difficult to remove. |
infinity focus, no glass to degrade image, manual focusing, stop down metering at shooting aperture
These are very useful adapters, allowing you to combine elements of SEVEN fantastic systems: Leica R, Leica Visoflex, Nikon F, Pentax Screw, Contax/Yashica, Olympus OM, and Canon EOS. The adapters themselves are precision machined and fit very well.
With the Visoflex and Pentax 42 adapters, they work easily by leaving the adapter on the body and changing lenses. With the other adapters, mount the adapter on the lens first, and then mount the lens and adapter on the camera. While it is feasible to use one adapter for many lenses, in practice it takes up a lot more time. It is much easier to remove the lens with adapter from the camera body, than it is to remove the adapter from the lens. IF you want to switch lenses quickly, use one adapter for each lens. The rear elements of some lenses, especially deep-seated wides, may hit the EOS mirror, so be careful. Yes, the adapters work with both film and digital EOS.
What functions will be available with these adapters on YOUR EOS camera body? As far as the camera is concerned, it does not have a lens on it -- just like when it is connected to a bellows. Check the instruction book to find out what functions YOUR camera body has when attached to a bellows.
Leica R Lenses: REOS, allowing R lenses to be used on your EOS in stop down mode. On most bodies this means you will be able to get manual exposure, aperture priority exposure, TTL flash. Mount your lenses on a digital EOS for digital SLR capability not yet available from Leica. The 19/2.8 R, the old 21/4 R mirror lockup, 24R, and 35/1.4 R can not be used on the EOS, as the deeply recessed rear element will strike the EOS mirror. This may also be true of other deeply recessed R lenses.
Pushing up the little lever on the left hand side of the pic unlocks the adapter, allowing its removal. Leica R 180/3.4 APO mounted on Canon EOS 3.
It will probably be easier to mount the adapter on your lens first, and then mount on the camera. For most EOS bodies, set the finder F/stop display to 1.0 or 0.0 for stop down metering.
IF you are using the large heavy Leica tele lenses which have both R and Visoflex mounts, it is probably wiser to use the Visoflex to EOS adapter as it is larger and likely stronger than the R to EOS adapter..
Leica M Visoflex Lenses: VEOS: As far as I am concerned, this adapter is a HUGE improvement over using Leica Visoflex mount lenses on ANY SLR, instead of using them on the awkward Visoflex/Leica M body combination they were designed for. More INFO here. Leica Visoflex lens to SLR body adapters are available in many different mounts. Mount your lenses on a digital EOS for digital SLR capability not yet available from Leica.
Nikon
F Lenses: NEOS, allowing Nikon F lenses (AF or manual focus) to be used on your EOS
in stop down mode. On most bodies this means you will be able to get
stop down manual
exposure, aperture priority exposure, TTL flash.
100/2 AF DC Nikkor mounted on EOS 3. Notice the metal lever just above the red dot in the rear mount picture. This is the adapter lock on the Nikon - EOS adapter. Push it in to unlock and remove the adapter.
By way of comparison, it runs over $700 to have your Nikon SLR converted to R mount, takes about four months to do, and is not reversible. A R to Nikon adapter won't do the job since the Nikon body is not thin enough to mount the adapter and still allow infinity focusing. Even then, the Nikon to R conversion doesn't give you lens to body coupling, either.
Pentax Screw Mount Lenses: PEOS, mounts Pentax 42mm screw mount lenses to be used on your EOS in stop down mode. On most bodies this means you will be able to get manual exposure, aperture priority exposure, TTL flash. It does not have a stop down ridge, which means its best suited for Pentax Takumar or similar lenses WITH a manual / auto diaphragm switch. If your lenses does not have manual / auto diaphragm switch, you will only be able to shoot at full aperture. The EOS digital bodies are by far the best digital options for your Pentax screw mount lenses.
Olympus OM Lenses: OEOS, mounts Olympus OM lenses very conveniently on the EOS via the adapter because of OM lens external stop down switch, allowing you to focus wide open and then quickly stop down to shooting aperture for metering and taking the shot. The EOS digital bodies are by far the best digital options for your manual focus Olympus OM lenses.
Contax/Yashica Lenses: CEOS, mounts manual focus Zeiss Contax RTS lenses on EOS. The EOS digital bodies are by far the best digital options for your manual focus Zeiss Contax/Yashica lenses.
Side Note: The manual focus R/FL/FD Canon series SLRs also accept Nikon F, Exakta, or Pentax Screw mount lenses with the correct classic, and now hard to find adapters.
